Abstract

The cloud delivery model for computing services offers cheap access to a variety of standardized services from various providers. But after outsourcing a service to the cloud, the owner no longer controls the platform on which the service runs. The user is bound to trust the cloud provider for correctness, privacy, and integrity of its data and computations. Cryptographic mechanisms can reduce such trust by allowing the user to protect its data and computations, as well as to verify aspects of remote computation. This presentation discusses a number of mechanisms for securing data stored in the cloud and for protecting computations running in the cloud.
